- This product in the mechanical, optical, light source on the use of unique, precise design, so that the indentation imaging more clear, more accurate measurement. The instrument adopts a closed-loop loading control system to improve the accuracy of the test force, and the repeatability and stability of the indication value are good. The new display screen LCD is used to display and the hardness scale HV or HK can be selected on the operation panel. The tested hardness value can be converted to each other.Equipped with 10 times digital measurement microscope and 20 times objective lens can participate in the measurement, so that the measurement range is wider, the application range is wider, the operation is more intuitive and clearer, the test method, test force, indentation length, hardness value, test force retention time, date, time, hardness conversion value and other functions can be displayed on the screen, and it has a threaded interface for connecting digital cameras and CCD cameras, easy selection of computer and hardness analysis and measurement software.
